Electric screw jack actuators is a basis jack-up part, accomplish the functions such as lifting, drop, push and inverting through worm gear drives screw.

The cubic screw jacks offer versatile mounting options and can be mounted upright or inverted to suit specific requirements.

Generally to say,manual screw jack is used when sluice gate is small and electricity is not available,while electric screw jack is used when the gate is heavy.

An integrated compact combination of ordinary tooth screw/ball screw/planetary ball screw, reducer and motor.

Screw jack is used in applications where linear motion is required. Lifting of any load, pushing or pulling of mechanical equipment, adjusting of tight clearances of mechanical parts can be done by screw jacks.

This heavy duty linear actuator is a powerful solution for pushing large loads.

Heavy Load Worm Gear Screw Jacks combine a machine screw jack, motor and gear reducer into a single compact unit.

The Crank Handle Screw Jack are ideal solutions for applications where electricity or power generators is inconvenient or dangerous, light weight, low duty cycle, low target cost and short travel length. The working principle of the hand operated worm gear screw jack is that the worm (also called the input shaft) is manually rotated by the hand wheel, the worm wheel is rotated by the worm, and the trapezoidal lifting screw is moved by the rotating worm wheel. The linear motion speed of the worm wheel manual screw jack trapezoidal lifting screw depends on the thread size and the worm gear speed ratio. Hand Operated Screw Jack is composed of hand wheel or hand crank and a worm gear screw jack.It is ideal solutions for applications where electricity or power generators is inconvenient or dangerous.
